Lore

Ruby
This Pokémon has a body of steel. To make its body, ARON feeds on iron ore that it digs from mountains. Occasionally, it causes major trouble by eating bridges and rails.

Sapphire
ARON has a body of steel. With one all-out charge, this Pokémon can demolish even a heavy dump truck. The destroyed dump truck then becomes a handy meal for the Pokémon.
